in Thoreau’s Journal:
A misty afternoon….This kind of weather is very favorable to our landscape. I must not forget the lichen-painted boles of the beeches….Surely I might take wider views. The habit of looking at things microscopically, as the lichens on the trees and rocks, really prevents my seeing aught else in a walk….
To the lichenist is not the shield (or rather the apothecium) of lichen disproportionately large compared with the universe?
